When working with multi-format
video material in the same session, consider the following:
You set the default timing for your project
when you assign it the resolution and frame rate at the time of
creation.
Even if a project has a specific timing
(resolution and framerate), it can contain clips of various resolutions.
You can input clips from any device supported
by your system's video board, but clips are captured at their native
device-based resolution and format.
You can output clips to any device supported
by your video board, but clips selected for output must be of the
resolution and format that correspond to the video timing of the
device.
You can change the video timing of your
VTR device without exiting your session, but to output to a VTR
of this timing, you must also change the corresponding hardware
connections.
The preview timing in the Preferences
menu is linked to the Clip Input menu. In other words, when you
change preview timing in the Preferences menu, the change is reflected
in the Clip Input menu.
Backdraft Conform checks if your video sync
matches the timing of the material you are working on when you load
a project on start-up, change projects in the Preferences menu,
change preview timing in the Preferences menu, or select an output
clip.
When a project is loaded or timing is
changed, Backdraft Conform selects an appropriate VTR for you, if necessary.
The VTR devices available depend on the VTR keyword lines uncommented
in the software initialisation configuration file.
